1. Grow cells to subconfluence in a flask.2. Harvest as per normal and count.3. Spin down 5min 1.2K in benchtop. Resuspend at 1.0 X 106/ml in 10% DMSO in media. This is prepared from frozen aliquotss of DMSO (essential to use tissue culture grade eg. DMSO Sigma D-2650, aliquoted and frozen at -70). Filter DMSO / media prior to resuspending cells in it.4.
